Application filed February 13, 1922 Serial No. 588,110.

To all whom it may concern:

Be it known that l, lsAAo'SNow, a citizen of the United States residing atlhawrence,

inthe countyolt Essex and State ofhfiassna 5 chusetts, have invented an improvement 1n Filling-iieplenishnig Looms of which the fOllOWlIlg description, n connection w th the i accoinpanylng; drawings, is a specification,

like characters on the drawingsrepres anting 110 like parts.

This invention relates to filling replenishing looms wherein anew supply offilling isiurnishedthe loom prior to the complete exhaustionof thelold filling.

usually provided with stopping mechanism forbringing the loom to rest on the occurrence of some fault, as for lnSilfLllCGtllG breakage of afwarpor filling thread. In

v zo such eases is customary for the loom atv tendant to move the shuttle home 1n the shuttle box by hand, so that on the following pick thepicking mechanism may serve toperiorm its picking function and throw the shuttle into the other box Whenthe loom-is againstartedby power ashy move ment or the stopping mechanlsm into looni running position, the shuttle may still contain a working supply of filling and under such cond1t1ons it s desirable that the filling replenishing mechanism may not operate to replen sh thefilllng Whenthe loom 1s started.

vcntion consists in means for preventing the replenishment oiiilling through the feeler and controlling means until after the. 100111 has been restored to full running condition. Incarrying this featureofthe invent on into v effect neansis PTOVldGCl to be positloned or actuated by movement otthe shipper into stopping position so constructed and ar ranged that the controlling mechanism for controllingreplenishment of filling will be rendered i'neilective for this purpose until. after the shipperhas been moved to loom running position. h i

In the present instance of the invention the feeler is inountedfor movement by the filling towards the front of the looni and also ina direction longitudinally of the shuttle box on a detecting heat before the shuttle comes to rest in the shuttle box. The construction is such that the feele'r acts p p In the drawings: Looms of thls general character a are p i in important feature of the presentin through the controlling mechanism to prevent replenishment oi? filling when the feeler is given its movement longitudinally of the shuttlebozr on a detecting heat, and to initiate replenishment otfilling when, upon substantial exhaustion of the filling in the shuttle the feeler fails to be rnoi 'edlongitudi nally of the shuttle box.

ilhenovel features of the present inventron and the new combination of parts will host 'be -inade'clear from thefollowing' description and accompanying drawings of one iornior embodiment thereof. i

Fig. l is a perspective View 111g side oi the loom showing the ieeler and associated parts. i i

ing; and t a v i Fig 4t 1s a plan view showing the leeler held or locked 1n its non-replenishing position by means actuated the stopping lli(3l1ttl11SII1 as the latter 1S moved into stopping position. i i v a 'lhe loo n iran e 1 has at each side thereof a bracket 2 prov ded w th bearings 3 one only of which shown, for the usual transverse or rock shaft 1:. Extending upwardly from the shaft is the arm to which is connected at 6 the arm 7, the rear end portion oisvhich is adapted to he engaged by an actuator 8. The actuator 8 may appropriately be formed as part of or connected to the weft hammer or cam follower, and

theconstruction is such that normally the flClSllfilZOlf 8 would strike and move the arm 7 to cause replenishment oi": filling unless, on

of the detect a detecting heat, the arm 7 is moved into inoperative relation with the actuator by the filling replenishing controlling; means.

' Pivotally mounted on the loom frame is a controller iftor controlling the position of theurni 7, and such controller is in turn gorernedby the feeler. In the present instance oi' the invention the controller conof: an arm 9 pivotally' supported on an axis 10 for rocking movement thereon, and

tion 12 of the controller, under the actuation of the spring 11 Willnormally hold the arm 7 in position to be engaged by the actuator 8.

The other end of the controller 9 is provided with a notched portion 13 having a cam surface 14-.

Mounted upon the loom frame is the feeler which has capacity for movement towards and from the front of the loom and also in a direction transversely of the loom or longitudinally of the shuttlebox.

In the present instance the feeler 15 is carried by a feeler stand 16 mounted adjustably on the loom frame by a bolt '17 passing through a slot '18 on the extended arm 19. The front end portion of the feeler passes through a rocking bearing 20 which is supported at its top and bottom portions for rocking movement by the bridge pieces 21, the construction being such that while the rocking bearing'20 may rock about its pivotal support 22, the feeler 15 may move in the slotted portion of the rocking bearing towards and from the'front of the loom.

The feeler-stand 16 hasa rear bearing portion 23 provided with 'an-elongated slot 2a through which the feeler extends, and a spring normally holds the feeler in its rearward feeling position. In the present instance this spring is shownat 25 one end of which is'connected adj'ustablyto an arm 26 by means of the openings 27 and the other end of the spring 25 is similarly connected to the feeleras 'at 28, the construction being suchth-at the spring 25 normally'acts tohold the feeler in its rearward feeling position and against one end of the elongated bearing slot 24,but with permissive movement of the feeler towards and from the frontof the loom and ina directionlongitudinally of-the shuttle box.

The lay 29 is of usual constructionandthe front wall of the shuttle box has an opening '30 through which the feeler projects to feel box, andi'f a working supply of filling is present-in the shuttle, the feeler 15 will be moved with the shuttlesas'itigoes fully home into the shuttle box.

llnder the conditions stated the 'Efeeler 15 :Wlll'I'lClQ along the cam portion 14 ofthe controller 9 and :turn the controller ClOClWVlSGOIi a detecting beat to thereby place the end of the arm 7 in an inparticular construction mechanism forms no essential part of the present invention, such mechanism is herein operative position with relation to the actuator 8.

Should the filling be substantially exhausted on a detecting beat. however. as indicated in Fig. 3, the feoler 15 will fail to be moved lon itudinally in the shuttle box by the shuttle as it goes fully home in the box and thereby the feeler will fail to turn the controller so that the end of the arm 7 will be engaged by the actuator 8. and through the usual train of mechanism will ellect replenishment of filling when the shuttle reaches the replenishing side of the loom.

In looms of this general type stopping mechanism is provided for stopping the loom when some fault occurs, as for instance. the lilQzlliflflljO of a warp thread, or of the tilling thread, or of the harness mechanism. Such stopping mechanism is of usual con struction and is controlled by a train of mechanism including a shipper. Since the of the stopping typified by the shipper 36 which, when the loom is running, is held in the notch 37 formed in the shipper stand. 38. When a fault o curs such as the bieaking of a warp thread, or a aveft thread, or of the harness connections. the shipper is thrown from its holding notch as usual in this class of looms and under the actuation of the usual shipper springthe shipper moves in the shipper slot 39 to the outer end portion thereof. I Advantage is taken of this movement of the shipper to render the filling replenishing controller means ineil'ectuahimd in the present instance the shipper stand has pivotally mounted thereon at 10 a bell crank lever, one end 41. of which is in the path of the shipper as it moves towards the outer end of the shipper notch, and the other end 42 of which carries a pin or roller 43 which, as the bell cranlrlever is-turned by engagement of the shipper with the end -l-l ot' the bell crank. renders the controlling mechanism ineffectual to replenish the filling.

In the present instance the bell crank -le= T01. has connectedthereto a spring-44L which normally holds the hell crank in theposition indicated by Figs. 1 and 2, with the end 41 of the hell crank crossing or partly crossing the shippcrnotch 39. shown in the present instance theroller 43 on the bell crank engages the side of the feeler '15 when the bell. crank is turned by the shipper. and thc feeler J5 is thereby moved .into its inclined V (.15. on to render ineffectual the filling rc i' lcnishing mechanism.

When a fault occurs in the operationof the loom, as for instance breakage or undue slackness of a warp thread, or from some other cause, and the shipper is disengaged "from its holding-notch as usual, it will enthe arm 41 of the bell crank as it moves iilenishingpositions V v a v The loom attendantniay now correct the mamas to the outer end of theshipperiiotclifturn lthe hellcrankuponits pivot and move the :iieeler 1nto-1ts inclined fault which causedloom stoppage and may hyghand move i theshuttle fully home in its 1 TSl'lLltlJlQbOX; lllen'illthenmove the shipper to loom running position as indicated in Fig.1., so that'on the first ClGlJQClIIIlg heat 'iolloiving restoration of the shippento loom running position, the ieeler Will be engaged by the filling in the shuttle and he to restore the bellncranlrto its cated, the feeler is provided Witha nemher or projection against which the roller 43 of theibell crank hears, the construction he j ingsuch that as the fcller moves frontimrdly ea shipper to loom running position the memon the first deterting beat after restoring the her or pin 45 on the teeler Will turn. the

hell crank or start it to turn and restore it to its normal position to thereby free the feeler and the controlling mechanism for effect ing replenishment of filling When, on a octecting beat, filling is substantially exhausted in the shuttle. i a

It maynot always be necessary toprovide the member or pin s5 on the feeler to -restore the hell crank to its inltial position but such ciimstruction desirable as a trip for the bell cranl; to restore it to normal position only upon the detecting heat following movement of the shipper to loom runn ngpositlon. 1 a
